DISCHARGING MECHANISM FOR ROTATING BORING-RODS.

$PECIFICATION forming part Of Letters Patent No. 650,988, dated June 5,1900.

Application filed Juno 9, 1899. Serial No. 719,985. (No model.)

To all whont it nutty concern:

Be it known that I, ANTON 'RAKY, a subject of the King of Prussia,German Emperor, and

a resident of Erkelenz, in the Province of 'the :Rhine, German Empire,have invented certain new and useful Discharging Mechanism f or RotatingBoring-Rods, of which the fol-f lowing is an exact specification.

The present'in-vention relates to an im-f structions the rope was fixedto the boring-rods and was led over a roller arranged in theboring-tower to the counterweight, which could;

move freely within a slide arranged on the boring-tower. In thesearrangements the boring-rodscould only elfect slight movements and veryoften had to be brought out of ac tion for a long time when thedischargingweightwas to be regulated. Generally the boring-rod afterhaving bored a hole of about one thousand feet depth had to be stoppedand the counterweight had to be regulated.

The advantage of my invention is that depths of great dimensions can bebored continually, the regulation of the counterweight being effectedduring the operation of the apparatus.

In order to render my invention more clear, I have represented,diagrammatically, three forms of execution in the accompanyingdrawings.

Figure 1 illustrates an elevational view of my invention. Figs. 2 and 3show the same on alargerscale. Fig. 4 is a top View of Figs. 1 and 2. 4

The counterweight g is suspended between two cylinders and Z. Thecylinder is is connected with a cylinderf, upon which is wound the roped, carrying the boring-rod a. Upon the second cylinderl the rope isWound in length corresponding to the depth of the hole to be bored,(generally corresponding to the length of the boring-rod.) The cylinderZ can be rotated by means of a foreshaft n, so as to bring down againthe weight 9 when it has attained its highest position and for the purbymeans of a gearing of conical wheels 0.

pose of allowing a corresponding length of rope to be unwound. Thus therotating boring-rod can descend more and more as long as rope is woundupon the roller Z. When this rope is unwound com pletely, the boringapparatus must be stopped. Then the cylinder 71'; has to be uncoupledfrom the cylinder f in the manner usually employed, and the appaofexecution is clearly represented in Fig. 3

of the accompanying drawings.

The boring-rod a reposes rotatably within a frame I). The rotatingmotionis given from the engine and transmitted to the boring-rod A rope01, running over the roller 6, arranged in the boring-tower, Fig. 1,carries at its one extremity the boring-rod and at the other is woundupon a cylinderf.

The counterweight g is suspended on a roller g of the rope 72 This ropeh is conducted over two rollers 1i and i, fixed to the frame of theboring apparatus, and at the oneside leads to a cylinder 70 and at theother side to a cylinder Z. In this form of execution the rope his notwound directly upon the cylinder carrying the rope d of the boring-rod,but the two cylinders taking up the carrier-rope for the boring-rod andthe rope to which is suspended the counterweight are brought intoconnection by a fore wheel m. This intercalating of a fore Wheel offersthe great advantage that the discharging of the weight of theboring-rods being comparatively great in a certain depth can be effectedVery easily. The cylinder Z, supporting the rope h to be unwound, can befixed by means of a worm-wheel n or can be rotated by the same. Also thecylinder 75 can be rotated in both directions by means of a hand-wheel1), connected to the cylinderk by an endless chain 0.

The operation of this apparatus is as follows: Suppose the weight of theboring-rod in a certain depth to be 4,405.3 pounds, the proportion oftransmission of m from k to f being as one is to twenty, not consideringthe resistance occurring by friction, the counterweight suspended on twosides only has to amount to 440.53 pounds in order to be equal to theweight of the boring-rod. By altering the effect of the counterweightthe operator is enabled to make the borer descend by its own weight, andat the same time the pressure which exercises the borer upon the rod canbe regulated at will. It now the counterweight is in its lowest positionand the boring mechanism is actuated, the boring-rod will descend slowlyand the rope d will be unwound from the cylinder f. Thereby the cylinderis rotated, so that the rope h is wound up and thedischarging-weightrises. Afterthe discharging-weight has attained itshighest position it must be brought back again into its originalposition by rotation of the cylinder Z, as before described. Thisrotation of the cylinder Z is effected by the worm-wheel n. The pressureof the boring-rod upon the rock can be regulated by means of the endlesschain 0, moved by the hand-wheel 1).

It very often happens that the borer suddenly meets a hard piece ofrock, so that a great pressure is necessary to attain a good boringeffect. Such hard pieces of rock generally being small, it isinadvantageous to modify the pressure of the borer by modification ofthe counterweight. In such cases the effect of the counterweight can beweakened or lessened by the hand-wheel p in increasing (by means of thefore wheel m) the pressure of the boring-rod. It is quite evident thatin the contrary eventi. 6., when the boring-rod meets softer pieces ofrock the eifect of the counterweight can be increased, and the pressureof the boring-rod will be weakened.

Figs. 1 and 2 represent an elevationalview of a modified form ofexecution of my invention. The general arrangement, the operation, andthe effect of this apparatus are the same as represented in Fig. 3. Adifference only consists in the special arrangement of the rope 7t,carrying the counterweight.

While in Fig. 3 the rope h is wound upon special cylinders 70 and Z, inthis construction no cylinders are used for this purpose, but the ropeis wound upon simple disks. The rope is endless and runs from the disk70, coupled to the cylinder f, over the roller i to the carrier roller 9of the counterweight. From there it is conducted over the roller 1) tothe disk Z, fixed or rotated by the worm-wheel gearing n. A guide-rollerq presses the rope it against the disk Z andleads the same downward andto arollerr,so thataloop h is formed between these rollers. The efiectis accurately the same as described in Fig.3. In the positionrepresented in Figs. 1 and 2 of the accompanying drawings thedischargingweight is lifted when the boring-rod descends deeper into thehole, and during this operation the loop h will be increased. When newthe weight g has attained its highest position, the disk Z is rotated inthe direction of the arrow, whereby the loop h is shortened and thecounterweight is brought down again, so that the disk 7c can continuethe lifting of the apparatus.

Having thus fully described the nature of this invention, what I desireto secure by Letters Patent of the United.States is In a dischargingmechanism for rotating boring-rods in apparatus fordeep borings, the

combination of a cylinder f taking up the free extremity of thecarrier-rope with a discharging-weight g suspended on arope hrunningover cylinders 70 and 6, means to connect the cylinder 76 to thecylinder f, means to rotate the cylinder Z and to fix the same, anendless chain 0 led over the cylinder 70, a hand-wheel p for givingmotion to the chain 0, for the purpose and substantially as set forth.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

ANTON RAKY.
